Abstract: (Physical Society of Japan)
We develop a dynamical coupled-channels (DCC) model for neutrino-nucleon reactions in the resonance region, by extending the DCC model that we have previously developed through an analysis of reaction data for W ≤ 2.1 GeV. We analyze electron-induced reaction data for both proton and neutron targets to determine the vector current form factors up to Q^2 ≤ 3.0 (GeV/c)^2. Axial-current matrix elements are derived in accordance with the Partially Conserved Axial Current (PCAC) relation to the πN interactions of the DCC model. As a result, we can uniquely determine the interference pattern between resonant and non-resonant amplitudes. Our calculated cross sections for neutrino-induced single-pion productions are compared with available data, and are found to be in reasonable agreement with the data. We also calculate the double-pion production cross sections in the resonance region, for the first time, with relevant resonance contributions and channel couplings. The result is compared with the double-pion production data. For a future development of a neutrino-nucleus reaction model and/or a neutrino event generator for analyses of neutrino experiments, the DCC model presented here can give a useful input.Note:
